Title: Manufacture of semiconductor device
Inventor: IWAKIRI TAKASHI
IPC: H01L21/301
Filed: 1996-10-02
Abstract: PROBLEM TO BE SOLVED: To greatly reduce a leak current by forming first to fourth layers on a region which is different from an element region of a substrate and covering a part to which unnecessary materials and adhered which is possibly remaining on the fourth layer with a mask material before removal of the fourth layer. SOLUTION: When a polysilicon layer 23 as a lower electrode of a capacitor is etched in a cylindrical shape, since an Si3 N4 layer 31 having eaves 31A is provided, a polysilicon layer 23 positioned just below is effectively protected by the eaves 31A. Even when the whole face of the polysilicon layer 23 is sufficiently etched, the polysilicon layer 23 can be selectively left on the outer faces of an Sil2 , layer 22 by an amount of the thickness below the eaves 31A. Consequently, even if a large step 14 exists on the semiconductor substrate, the polysilicon layer 23 is sufficiently etched and removed also in the step 14 and a residual 13 does not remain. A memory cell which can, therefore, always operate normally can be realized.

IPC: G11B5/39
Filed: 1993-10-15
Abstract: PURPOSE:To improve the dielectric withstand voltage between the shielding layer and electrode layer of the thin-film magnetic head constituted by using a magneto-resistance effect element. CONSTITUTION:A lower insulating layer 11 is formed on the surface of a lower shielding layer 3 consisting of plating 'PermalloyR '''and another insulating layer 21a is formed thereon. An insulating layer 21b for determining a track width Tw is formed at the center of the front surface of the MR element 12. The insulating layer 21a and the insulating layer 21b are the same films and are separated by etching grooves 22, 22. The dielectric withstand voltage is improved by forming the double insulating layers 11 and 21a between the lower shielding layer 3 and the electrode layer 23. The insulating layer 21a is formable simultaneously with the insulating layer 21b for determining the track width Tw and, therefore, there is no need for separately providing a stage for forming the insulating layer 21a.

Title: On-line program generation system
Inventor: AMAMIYA MAYUMI
IPC: G06F9/06
Filed: 1988-11-08
Abstract: PURPOSE:To reduce the time of generation and test by updating the record of a key given from a screen for a transaction file and compiling a program source after the screen is defined. CONSTITUTION:An on-line program generation pattern being the program source is transferred to a source unit library. The record is updated by a content in which the source unit library is punched and registration is performed for the source unit library by a new name. When the program source of the source unit library is compiled, screen definition is developed, is sent to a load module library and a system is set to a performable state. Thus, an on-line program can easily be generated only by changing the conditions such as a screen definition name, an objective file name, a reading method and the contents of generation or correction. Furthermore, the test time is shortened since a fundamental part is not altered.
